Viggo, also spelled Wiggo, is a Nordic male name. There are two main theories about its origins:
- a latinised form of the Old Norse name Viggeir, which is also found in the form of other Germanic names, such as Ludvig. It stems from old Norse vig-, meaning "battle, fight".
- a variant of the Icelandic name Vöggur, coming from old Norse 'vöggr', "one who lies in a cradle".
